Project Description I am developing a compact handheld mechanical device that transitions between two physical size configurations. The device must: • Collapse into a short, compact configuration • Extend into a longer ergonomic handheld configuration • Use a deliberate twist action to lock in both positions • Remain durable and mechanically stable in both states • Be compact, lightweight, and suitable for field use The mechanism should not rely on springs or automatic deployment. The transition between positions should be manual and intentional. The device will ultimately attach to a wearable platform, but the focus of this stage is the device body and locking mechanism, not the wearable system. Materials under consideration include: • aluminum • ...

We need a board that "translate" signal from DMX to led strip pixel adressable. Need to integrate RGB and RGBW pixel in various protocol, with clock or only data. Only one data signal needed (170 rgb pixel or 128 rgbw pixel to complete universe) -Possibilities to set start adress -Possibilities to control multiple pixel as one pixel (grouping for have total of 2x or 3x o 4x pixel controlled) -Setting IC ,Address and Grouping by dipswitch or other way accepted (also usb serial with proprietary software) -ALL SETTINGS NEED ALSO TO BE SETTED BY RDM -Usb or serial connector for upload firmware We are open to every system from arduino to anything. Need to be thinked in hardware and software side. Other this one we need a variant with pwm rgbw output with same feature like RDM, ...

I’m ready to move an industrial-grade controller from concept to production and need a designer who has already shipped tight, 6-layer boards. The board must host a main microcontroller, its support circuitry, and several high-current power-regulator stages, all within a restricted outline while meeting EMI/EMC limits typical for factory environments. You’ll start from my block diagram and rough schematic notes, turn them into a production-ready layout, and supply every file the assembly house will ask for: updated schematics, stack-up, Gerbers, drill files, pick-and-place, BOM, and a brief design report explaining how the EMC strategy and size targets were achieved. I’ll be available for rapid feedback on component placement and routing choices, and we’ll sign ...

Description Of Project - HRID-AI is a low cost handheld device aimed at estimating ejection fraction using multimodal biosignals (ECG, seismocardiography, and cardiac acoustics). It uses a combination of biosensors to detect abnormalities in ECG, presence of abnormal heart sounds and their interpretation as well as usage of seismocardiographic signals to provide an estimate of Ejection Fraction. The principle has been verified through multiple studies done in reputed institutions The goal is rapid point-of-care triage for echo referral in emergency and low-resource settings in patients of Heart Failure with Reduced Ejection fraction We need your support, skills and expertise for sensor integration, embedded design, signal acquisition. Current Status- We have so far been able to dev...
